您好，和Excel一样，可以添加数据验证
gcSpreadSheet1.HighlightInvalidData = true;
var valid = GrapeCity.Windows.SpreadSheet.Data.DataValidator.CreateListValidator("5,10,15,20");            
gcSpreadSheet1.Sheets.Cells.DataValidator = valid;
gcSpreadSheet1.Sheets.Cells.Text = "5, 10, 15, and 20 are valid numbers.";
            
var valid1 = GrapeCity.Windows.SpreadSheet.Data.DataValidator.CreateNumberValidator(GrapeCity.Windows.SpreadSheet.Data.ComparisonOperator.GreaterThan, "5", "20", true);
gcSpreadSheet1.Sheets.Cells.DataValidator = valid1;
gcSpreadSheet1.Sheets.Cells.Text = "A number greater than 5 is valid.";

var valid2 = GrapeCity.Windows.SpreadSheet.Data.DataValidator.CreateTextLengthValidator(GrapeCity.Windows.SpreadSheet.Data.ComparisonOperator.GreaterThan, "4", "20");            
gcSpreadSheet1.Sheets.Cells.DataValidator = valid2;
gcSpreadSheet1.Sheets.Cells.Text = "Type more than four characters.";
